Four-legged security teams join response as Woolworths tightens safety measures after explosions.

From wagging tails to highly trained noses, a special team of four-legged security experts spent the weekend helping to protect Woolworths stores across South Africa following recent explosions at two branches.

The retailer shared a glimpse of the heightened security measures, revealing that sniffer dogs and their handlers had been deployed to stores around the country after explosive devices detonated at Woolworths stores at Menlyn Park Shopping Centre in Pretoria and Preller Square Shopping Centre in Bloemfontein last week.

In a message to customers, the company thanked the canine teams for their work.

"Hi Woolies shoppers, this weekend we had a few esteemed guests in attendance at stores across the country."
